are these the right manifolds

They do look correct as the driver side needs an extreme pinch for the steering as yours do, 600 is a steal. Now that I read that all B/RB A manifolds are all different, you would want the right ones. Expect to pay like $4K for the 440 ones. Thats nuts.

Warning: Accurate LTD repops a modded 383-Abody manifold, yours look too good to be true OEM.
